[ TONE Generation ] PCM - ADPCM

Started by Dhiraviam Natarajan September 13, 2003
Hi ppl,

I working on tone generation for an Access Network ( of a telephone exchange ).

Can some one throw light on PCM to ADPCM conversion algorithm , point me some
useful web tutorials / links. Can ADPCM samples be generated directly by any
means ?

Generally, a simple sine function is used to generate tones. Is that always
sufficient? Is there any other means to generate tone?

I would appreciate any help in this regard. Thanks a lot, in advance.
